Division 7.2 Principle of emission measurement

To measure the brake-specific emissions, the engine shall be operated over the test cycles defined in point 7.4, as applicable. The measurement of brake-specific emissions requires the determination of the mass of pollutants in the exhaust emissions (i.e. HC, CO, NO_x and PM), the number of particulates in the exhaust emissions (i.e. PN), the mass of CO₂ in the exhaust emissions, and the corresponding engine work.
